Multiple integer overflows in the JBIG2 decoder in
Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, and
other products allow remote attackers to cause a denial
of service (crash) via a crafted PDF file, related to (1)
JBIG2Stream::readSymbolDictSeg, (2) JBIG2Stream::readSymbolDictSeg,
and (3) JBIG2Stream::readGenericBitmap. (CVE-2009-0146, CVE-2009-0147)

Integer overflow in the TIFF image decoding routines in CUPS 1.3.9 and
earlier allows remote attackers to cause a denial of service (daemon
crash) and possibly execute arbitrary code via a crafted TIFF image,
which is not properly handled by the (1) _cupsImageReadTIFF function
in the imagetops filter and (2) imagetoraster filter, leading to a
heap-based buffer overflow. (CVE-2009-0163)

Integer overflow in the JBIG2 decoder in Xpdf 3.02pl2 and earlier,
as used in Poppler and other products, when running on Mac OS X,
has unspecified impact, related to g*allocn. (CVE-2009-0165)

The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier,
and other products allows remote attackers to cause a denial of service
(crash) via a crafted PDF file that triggers a free of uninitialized
memory. (CVE-2009-0166)

The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier,
Poppler before 0.10.6, and other products allows remote attackers to
cause a denial of service (crash) via a crafted PDF file that triggers
an out-of-bounds read. (CVE-2009-0799)

The ippReadIO function in cups/ipp.c in cupsd in CUPS before 1.3.10
does not properly initialize memory for IPP request packets, which
allows remote attackers to cause a denial of service (NULL pointer
dereference and daemon crash) via a scheduler request with two
consecutive IPP_TAG_UNSUPPORTED tags. (CVE-2009-0949)

The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier,
Poppler before 0.10.6, and other products allows remote attackers to
execute arbitrary code via a crafted PDF file that triggers a free
of invalid data. (CVE-2009-1180)

The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier,
Poppler before 0.10.6, and other products allows remote attackers to
cause a denial of service (crash) via a crafted PDF file that triggers
a NULL pointer dereference. (CVE-2009-1181)

The JBIG2 MMR decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and
earlier, Poppler before 0.10.6, and other products allows remote
attackers to cause a denial of service (infinite loop and hang)
via a crafted PDF file. (CVE-2009-1183)

Two integer overflow flaws were found in the CUPS pdftops filter. An
attacker could create a malicious PDF file that would cause pdftops
to crash or, potentially, execute arbitrary code as the lp user if
the file was printed. (CVE-2009-3608, CVE-2009-3609)

This update corrects the problems.
